Safety Instructions

Use the following safety guidelines to help ensure your own personal safety and to help protect

your system and working environment from potential damage. For complete safety information,

see the

Product Information

Guide

.

SAFETY: Rack Mounting of Systems

Observe the following precautions for rack stability and safety.

Systems are considered to be components in a rack. Thus, "component" refers to any system as well

as to various peripherals or supporting hardware.

CAUTION: Before installing systems in a rack, install front and side stabilizers on stand-alone racks

or the front stabilizer on racks joined to other racks. Failure to install stabilizers accordingly before

installing systems in a rack could cause the rack to tip over, potentially resulting in bodily injury under

certain circumstances. Therefore, always install the stabilizer(s) before installing components in the

rack.

CAUTION: After installing system/components in a rack, never pull more than one component out of

the rack on its slide assemblies at one time. The weight of more than one extended component could

cause the rack to tip over and injure someone.

NOTE: Your system is safety-certified as a free-standing unit and as a component for use in a rack

cabinet using the customer rack kit when both the rack cabinet and rack kit were designed for your

system. The installation of your system and rack kit in any other rack cabinet has not been

approved by any safety agencies. It is your responsibility to have the final combination of system

and rack kit in a cabinet evaluated for suitability by a certified safety agency. The manufacturer

disclaims all warranties and liability in connection with such combinations.

•

System rack kits are intended to be installed in an approved rack by trained service

technicians. If you install the kit in any other rack, be sure that the rack meets the

specifications.

• Before working on the rack, make sure that the stabilizers are secured to the rack, extended to

the floor, and that the full weight of the rack rests on the floor. Install front and side stabilizers

on a single rack or front stabilizers for joined multiple racks before working on the rack.

• Always load the rack from the bottom up, and load the heaviest item in the rack first.

• Make sure that the rack is level and stable before extending a component from the rack.

• Do not overload the AC power supply branch circuit that provides power to the rack.

The total rack load should not exceed 80 percent of the branch circuit rating.

• Ensure that proper airflow is provided to components in the rack.

• Do not step on or stand on any system/component when servicing other systems/components

in a rack.

6 Rack Installation Guide

Installation Instructions

This installation guide provides instructions for trained service technicians installing one or more

systems in an open-frame relay rack or in a rack cabinet. The RapidRails™ rack kit can be installed

without tools in manufacturer’s rack cabinets that have square holes; the VersaRails™ rack kit can

be installed in most industry-standard rack cabinets that have square or round holes. The

procedures for installing both RapidRails and VersaRails rack kits are similar. One rack kit is

required for each system installed in the rack.

CAUTION: Do not install rack kit components designed for another system. Use only the rack kit for

your system. Using the rack kit for another system may result in damage to the system and personal

injury.

The VersaRails rack kit can be installed in most industry-standard rack cabinets.

NOTICE: The VersaRails rack kit is intended to be installed by trained service technicians in a rack that

meets the specifications of American National Standards Institute (ANSI)/Electronic Industries

Association (EIA) standard ANSI/EIA-310-D-92, International Electrotechnical Commission (IEC) 297, and

Deutsche Industrie Norm (DIN) 41494. One rack kit is required for each system that is installed in a rack.

Before You Begin

Before you begin installing your system in the rack, carefully read "Safety Instructions," found

earlier in this guide, as well as the safety instructions found in your

Product Information Guide

for

additional information.

CAUTION: When installing multiple systems in a rack, complete all of the procedures for the current

system before attempting to install the next system.

CAUTION: Rack cabinets can be extremely heavy and move easily on the casters. The cabinet has no

brakes. Use extreme caution while moving the rack cabinet. Retract the leveling feet when relocating

the rack cabinet. Avoid long or steep inclines or ramps where loss of cabinet control may occur. Extend

the leveling feet for support and to prevent the cabinet from rolling.

Important Safety Information

Observe the safety precautions in the following subsections when installing your system in the rack.

CAUTION: You must strictly follow the procedures in this document to protect yourself as well as

others who may be involved. Your system may be very large and heavy, and proper preparation and

planning are important to prevent injury to yourself and to others. This becomes increasingly important

when systems are installed high up in the rack.

Rack Stabilizer Feet

CAUTION: Before installing systems in a rack, install front and side stabilizers on stand-alone racks

or the front stabilizer on racks joined to other racks. Failure to install stabilizers accordingly before

installing systems in a rack could cause the rack to tip over, potentially resulting in bodily injury under

certain circumstances. Therefore, always install the stabilizer(s) before installing components in the

rack.

Rack Installation Guide 7

CAUTION: After installing systems in a rack, never pull more than one system out of the rack on its

slide assemblies at one time. The weight of more than one extended system could cause the rack

to tip over and cause injury.

The stabilizer feet help prevent the rack from tipping over when a system or other component is

pulled out of the rack with the slide assemblies fully extended. See the documentation provided

with the rack cabinet for instructions on installing and anchoring the stabilizer feet.

Removing the Rack Doors

See the procedures for removing doors in the documentation provided with your rack cabinet.

CAUTION: Because of the size and weight of the rack cabinet doors, never attempt to remove or install

them by yourself.

CAUTION: Store the two doors where they will not injure someone if the doors accidently fall over.

Marking the Rack

You must allow 7 U (31.1 cm or 12.25 inches) of vertical space for each system you install

in the rack (see Figure 1-3).

NOTE: Your rack may already be marked and not require this procedure.

CAUTION: If you are installing more than one system, install the rail assemblies so that the first system

is installed in the lowest available position in the rack.

1

Place a mark on the rack’s front vertical rails where you want to locate the bottom

of the system you are installing in the rack cabinet.

The bottom of each 1-U space is at the middle of the narrowest metal area between holes

(marked with a horizontal line on some rack cabinets—see Figure 1-3).

2

Mark the rack’s front vertical rails with a felt-tipped pen or masking tape approximately 31.1

cm (12.25 inches) above the original mark you made (or count up 21 holes in a rack that

meets EIA-310 standards). (If you counted holes, place a mark just above the top hole.)

This mark or piece of tape indicates where the system’s upper edge will be located on

the vertical rails (see Figure 1-4).

Figure 1-4. Marking the Vertical Rails

Installing the RapidRails Assemblies

1

At the front of the rack cabinet, position one of the RapidRails assemblies so that its

mounting-bracket flange fits in the appropriate location on the rack (see Figure 1-5).

The lower mounting hook on the rail assembly’s front-mounting bracket flange should enter

the third hole up from the bottom mark on the vertical rails.

2

Push the rail assembly forward until the top mounting hook enters the square hole just below

the upper marks or tape you placed on the vertical rail. Next, push down on the mounting-

bracket flange until the mounting hooks seat in the square holes and the push button pops

out and clicks (see Figure 1-5).

3

At the back of the cabinet, pull back on the mounting-bracket flange until the mounting

hooks are in the appropriate holes, and then push down on the flange until the mounting

hooks seat in the square holes and the push button pops out and clicks.

4

Repeat steps 1 through 3 for the rail assembly on the other side of the rack.

NOTE: Ensure that the rails are mounted at the same vertical position on both sides of the rack.

Figure 1-5. Installing the RapidRails Assemblies

Installing the VersaRails Assemblies

1

At the front of the rack cabinet, place a VersaRails assembly so that its mounting-bracket

flange fits between the marks or tape (or numbered location) on the rack (see Figure 1-6).

The holes on the front of the mounting bracket should align with the holes between

the marks on the front vertical rail.

2

Install three 10-32 x 0.5-inch flange-head Phillips screws to secure the rail assembly

to the front vertical rail (see Figure 1-6).

14 Rack Installation Guide

2 Using the following guidelines, secure the cables to the rack’s back vertical rails using

the four releasable tie-wraps supplied in the rack kit (see Figure 1-8).

– To improve serviceability and airflow, create two bundles of cables on each side of the

system, keeping the area directly in back of the system as clear of cables as possible.

– Create separate bundles of cables for the I/O cables and the power cables.

– If the cables are sufficiently flexible, leave 10–15 cm (4–6 inches) of slack in the cables

between the cable tie and the system, to improve serviceability of the modules.
